- According to ICRP Publication 103, the recommended maximum permissible annual radiation dose for occupational radiation workers is 20 mSv averaged over 5 years, with no single year exceeding 50 mSv.
- This limit balances the need to protect workers from harmful effects of ionizing radiation while allowing sufficient exposure for professional duties.
- The 20 mSv/year limit is designed to minimize the risk of radiation-induced cancer and genetic damage, ensuring safety without unnecessarily restricting occupational activities.
